31c5632840 Decode configuration for the IDE part of the Triton chipset. This
includes a hack in the probe code: the 82371FB is a multifuction
device, but doesn't properly set the configuration bit which
indicates this.  So, we just hard-wire all 82371FBs as multifunction
devices.

This does not actually make the bus-master IDE stuff work, although
if anyone wants to work on that, I have the databooks that tell
how to use it.

984afdcfd2 The Great Merge.
The worm driver is alpha-usable!  I've stuffed everything that is
needed into the kernel driver, including the logic to select
between different vendor's quirks.

Disclaimer: this has by now _only_ been tested on a heavily tweaked
2.0.5R system.  I've done my best to retrofit it into -current, but
i don't have a chance yet to test it in a -current environment.

af4cb3a1c4 [Oops, forgot to commit this together with things that depend on it.]
First attempt at creating devfs entries for sliced devices.  Doesn't
quite work yet, so the heart of it is disabled.

Added bdev and cdev args to dsopen().

Create devfs entries in dsopen() and (unsuccessfully) attempt to make
them go away at the right times.  DEVFS is #undefed at the start so
that this shouldn't cause problems.

dd87702a51 Allocate DMA bounce buffers only when requested by drivers. Only the
fd and wt drivers need bounce buffers, so this normally saves 32K-1K
of kernel memory.

Keep track of which DMA channels are busy.  isa_dmadone() must now be
called when DMA has finished or been aborted.

Panic for unallocated and too-small (required) bounce buffers.

fd.c:
There will be new warnings about isa_dmadone() not being called after
DMA has been aborted.

sound/dmabuf.c:
isa_dmadone() needs more parameters than are available, so temporarily
use a new interface isa_dmadone_nobounce() to avoid having to worry
about panics for fake parameters.  Untested.

6139755401 Fixed allocation of DMA buffers. The DMA bounce buffers were sometimes
overrun by 2 pages.

Fixed the (unused) values returned from device attach functions.

Fixed checking of unit number in device open functions - don't load bad
pointers or print error messages about the contents of bad pointers.

Removed unused #includes.

asc.c:
Fixed premature setting of flags in ascopen() - copied the better order
in gscopen().

gsc.c:
Fixed conflict handling for drq:
- fail the probe if the configured drq doesn't match the actual drq.
- set the configured drq to match the actual drq in the autoconfig case.

324e9ed2a4 Added a `boundary' arg to vm_alloc_page_contig(). Previously the only
way to avoid crossing a 64K DMA boundary was to specify an alignment
greater than the size even when the alignment didn't matter, and for
sizes larger than a page, this reduced the chance of finding enough
contiguous pages.  E.g., allocations of 8K not crossing a 64K boundary
previously had to be allocated on 8K boundaries; now they can be
allocated on any 4K boundary except (64 * n + 60)K.

Fixed bugs in vm_alloc_page_contig():
- the last page wasn't allocated for sizes smaller than a page.
- failures of kmem_alloc_pageable() weren't handled.

Mutated vm_page_alloc_contig() to create a more convenient interface
named contigmalloc().  This is the same as the one in 1.1.5 except
it has `low' and `high' args, and the `alignment' and `boundary'
args are multipliers instead of masks.

7c399a896a Delete the if_private[] array in struct ifnet; this turned out to be
of limited utility.  In their place, add bunch of pointers
which will eventually be needed by the polled-interrupt scheme we're working
here.  (It will probably be a while before the code is written and
committed here.)  At the same time, a `void *if_softc' field
was added to the beginning of the structure to make certain driver
writers happier.

The practical upshot of all this is that you need to
recompile utilities such as netstat which manipulate struct ifnet.

f863805df0 This time, really make the procfs work when reading stuff from the UPAGES.
This is a really ugly bandaid on the problem, but it works well enough for
'ps -u' to start working again.  The problem was caused by the user
address space shrinking by a little bit and the UPAGES being "cast off" to
become a seperate entity rather than being at the top of the process's
vmspace.  That optimization was part of John's most recent VM speedups.

Now, rather than decoding the VM space, it merely ensures the pages are
in core and accesses them the same way the ptrace(PT_READ_U..) code does,
ie: off the p->p_addr pointer.

97f1b9871e Add a check to prevent a computation from underflowing and causing
a panic due to an attaempt to allocate a buffer for a terabyte or
so of data when an attempt is made to create sparse data (e.g.
a holey file) more than 1 block past the end of the file.

Note:  some other areas of this code need to be looked at,
since they might cause problems when the file size exceeds 2GB,
due to storing results in ints when the computations are being
done with quad sized variables.

0cc7521383 Major fixes for procfs..
Implement a "variable" directory structure. Files that do not make
sense for the given process do not "appear" and cannot be opened.
For example, "system" processes do not have "file", "regs" or "fpregs",
because they do not have a user area.

"attempt" to fill in the user area of a given process when it is being
accessed via /proc/pid/mem (the user struct is just after
VM_MAXUSER_ADDRESS in the process address space.)

Dont do IO to the U area while it's swapped, hold it in place if possible.

Lock off access to the "ctl" file if it's done a setuid like the other
pseudo-files in there.

PT_{GET|SET}{REGS|FPREFS} implemented now, using code shared with procfs
PT_{READ|WRITE}_{I|D} now uses code shared with procfs
ptrace opcodes now fully permission checked, including ownerships.
doing an operation to the u-area on a swapped process should no longer
panic.
running gdb as root works for me now, where it didn't before.
general cleanup..

Note, that this has some tightening of permissions/access checks etc.
Some of these may be going too far..  In particular, the "owner" of the
traced process is enforced.  The process that created or attached to
the traced process is now the only one that can "do" things to it.
